我错了什么？（表格确认） [英] What am I getting wrong?(Form validation)

问题描述

以下是表单验证代码的一部分。代码段应该验证URL。

  else  if（$ Key ==   Website ||  $ Key  ==  目的地 ||  $ Key  ==  来源）
 {
  if （！preg_match（  / \b |（:( ?: HTTPS FTP？）：\？/ \ / | www\） - α-Z0-9 +&安培; @＃\ /％=〜_ |！： ，。;] * [ -  a-zA-Z0-9 +& @＃\ /％= ~_ |] / i，$ Data [$ Key]））
 {
 $错误[$ Key] =  无效的网址。; 
  $ Return  =  1 ; 
} 
} 

调试工作表明代码报告错误当它从表单输入中读取以下URL时：

 <  输入    type   = 隐藏    value   =  GetAffiliatelink.php   名称  = 目的地  /  >  
 <  输入   < span class =code-attribute> type   =  hidden    value   =  ProductAffiliate.php #Advote％20School％20Pedestal    name   = 来源  /  >  

请注意，为什么网址无效。我一直在看代码几个小时，找不到任何错误。有人可以帮我看看吗？

解决方案

Key == 网站 ||

Key == 目的地 ||

Key == Source）
{
if （！preg_match（ / \b（？:(？：https？| ftp）：\ / \ / | www \。）[ - a-z0-9 +& ？！; @＃\ /％=〜_ |：;] * [ - α-ZA-Z0-9 +&安培; @＃\ /％=〜_ |] / I，

The following is a part of a form validation code. The code segment is supposed to validate URL's.

else if($Key == "Website" || $Key == "Destination" || $Key == "Source")
							{
								if (!preg_match("/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-zA-Z0-9+&@#\/%=~_|]/i",	$Data[$Key]))
								{
									$Error[$Key] = "Invalid URL.";
									$Return = 1;
								}
							}

Debugging effort shows that the code reports an error when it reads the following URL from form inputs:

<input type="hidden" value="GetAffiliatelink.php" name="Destination"/>
								<input type="hidden" value="ProductAffiliate.php#Promote%20School%20Pedestal" name="Source"/>

Please why is it stating that the url's are not valid. I have been looking at the code for hours and can't find any bug. Can someone kindly help me give it a look?

解决方案

Key == "Website" ||

Key == "Destination" ||

Key == "Source") { if (!preg_match("/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-zA-Z0-9+&@#\/%=~_|]/i",
